Running Batch wizard on https://www.newcastlecameraclub.org/ is giving me several 508 - Loop Detected messages. As far as I can tell, these are just links to other pages on the site, or links to the same page, but all of them would require the user to click on a link. Is it telling me about something I need to fix, or something that might need fixing?

Can you try slowing down the link checker? Go to the Validator Engine Options and the 'Link Checking' page and try changing the wait time between checks to 1000 milliseconds or more and lowering the max simultaneous link checks to 5. Then run the job again. Does that have any effect?
